TESTING THE SEQUENTIAL LOGIT MODEL AGAINST THE NESTED LOGIT MODEL*

In this paper, we show that the sequential logit (SL) model, in which a choice process is characterized as a sequence of independent multinomial logit models, is a limiting case of the nested logit (NL) model. For testing the SL model against the NL model, we propose Wald, likelihood ratio and Lagrange multiplier tests after suitably reparameterizing the NL model. It is found that when the NL model parameters are “weakly identified”, the Wald test severely underrejects the true model, whereas the sizes of the LR and LM tests are not significantly affected.     

EMERGENCE OF LEADERSHIP IN TEAMS*

This paper provides a simple model to explain the emergence of leadership in an unstructured team. Each agent has partial information about the productivity of the team. Each agent may invest a productive effort in one of two periods. If one agent voluntarily moves first and the other waits for the second period, and if the first‐move action successfully transmits his type, the first mover effectively exercises leadership in affecting the effort choice of the second mover. We prove that, if each agent holds stochastically independent information, leadership emerges with positive probabilities in Cho–Kreps stable outcomes.     

WEALTH EFFECT OF PUBLIC FUND INJECTIONS TO AILING BANKS: DO DEFERRED TAX ASSETS AND AUDITING FIRMS MATTER?*

This paper examines the wealth effect on other banks by the public fund injection into Resona Bank. This paper finds that the injection initially conveyed the auditing firms' strict stance towards deferred tax assets. More importantly, the procedure that the government employed was regarded by market participants as a too‐big‐to‐fail policy. Therefore, although the Resona injection was effective in obviating a financial crisis, the policy was inevitably accompanied with the moral hazard problem.     

ENDOGENOUS FERTILITY AND THE CONSUMPTION TAX*

The differential incidence between the consumption tax and the labour income tax is examined in a model where altruistic parents decide the number of children endogenously. In contrast with past results, the consumption tax is not neutral and exerts distortional effects. As a result, welfare gets worse off through the tax reform of switching from a labour income tax to a consumption tax. This provides the argument about the treatment of bequests under a consumption tax.     

THE EMPLOYMENT AND WAGE SYSTEMS IN POSTWAR JAPAN

This paper presents an analysis of the systems of employment and wage decisions in, for the most part, large-scale enterprises in Japan, and of changes therein as well as of the controlling factors. Hence particular attention is paid to the systems of temporary and external employees hired by subcontractors, lifetime employment, and seniority wages (by length of service). While there is obviously no doubt that these are characteristically Japanese systems, they can be regarded as reflecting nothing more than the fact that in Japan the operation of some of the various general factors which control the labor market is particularly strong while the operation of other such factors is especially weak. And these systems are being altered, having taken on Japanese forms.     

Debt Overhang and Lack of Lender's Commitment

The debt overhang of sovereigns or firms is modeled in the recent literature as a constrained efficient outcome of dynamic debt contracts under the lack of the borrower's commitment, where debt relief is not Pareto-improving. The early literature observes another type of debt overhang where the borrower is discouraged from expending effort, anticipating the lender to take all output ex post. We show that this inefficiency is due to the lack of the lender's commitment and debt relief is Pareto-improving. Nevertheless, debt overhang may persist, as frictional bargaining over debt relief can take a long time.
